I just saw a pop-corn popper that would serve as a coffee roaster, except that it holds five liters. Roasting more than a pint or so of coffee at a time seems to me counterproductive.
Is there a practical device of this kind available for coffee lovers? If there is not an attractive electric one, can one still find the little stove-top covered pans with an agitator inside. Fifty years ago, these little roasters made many (maybe most) kitchens in Italy smell great.
